Abstract (en)
A microchip laser comprises first and second mirrors at spaced locations along an optical axis and defining a resonance cavity therebetween. A gain element formed of a gain material is located in the cavity. Spacing means providing a temperature dependent distance of separation between the mirrors which is greater than the axial thickness of the gain element such that a variable gap is defined between the first mirror and a first face of the gain element are also provided along with temperature regulating means operable to control the temperature of the gain element and the spacing means. <IMAGE>
